FUNCTION<br />
The hydraulic unit for underfloor heating/cooling systems is a set of components containing the hydraulic elements required for<br />
the underfloor heating circuit. The hydraulic units pump the water channelled towards the underfloor heating circuit and regulate<br />
its temperature.<br />

COMPONENTS<br />
Components and functions:<br />
1. Mixer:<br />
The mixer regulates the temperature of<br />
the underfloor heating circuit. There are<br />
two types:<br />
a. Single point mixer. This is a manual<br />
mixer that can mix water within a<br />
temperature range of 25-55ºC.<br />
b. Variable point mixer. This mixer<br />
is powered by a 230V electric<br />
motor. With the aid of a central<br />
unit and an external sensor, the<br />
variable point mixer regulates the<br />
flow temperature according to the<br />
exterior temperature.<br />
2. Pump: Types: see catalogue.<br />
3. Shut-off valves with thermometers (flow<br />
branch).<br />
4. Differential pressure valve. This valve<br />
has a calibration range of 0.1-0.6 bar.<br />
(Optional)<br />
5. Shut-off valves with thermometers (flow<br />
and return branches).<br />
6. Insulating casing in expanded<br />
polypropylene (EPP).<br />
7. Wall mounting support.<br />
